Lake Island is an island on the coast of the Canadian province of British Columbia. It is located between Mathieson Channel and Lady Trutch Passage.[1]
Lake Island is part of a volcanic area called the Milbanke Sound Group and includes monogenetic cinder cones. Basaltic tuff breccias on Lake Island originated from Helmet Peak.[2]
